I'm a little confused by this patch, because it is very different from
Motorola's application note AN1800/D (Programming the Thermal Assist
Unit in the MPC750 Microprocessor).

1) No calibration. The board vendor is supposed to calibrate the TAU
before shipping the board, then supply the calibration value. I'm not
sure whether Apple do this.
2) Why all the time spent doing bit reversals? Why not just fix the
broken values in processor.h and test the correct bits to start with?
